Now Hershey's has the perfect countdown to Christmas for any peanut butter fan: a Reese's Advent calendar filled with chocolate and peanut butter!

What's in a Reese's advent calendar?

The most genius part of the Hershey's invention is that you don't have to pick favorites between Reese's Pieces and Reese's peanut butter cups. The calendar includes six of the mini peanut butter cups and 18 packets of Reese's Pieces, so you're in for a surprise every time you open one of the candy windows.

Of course, if one peanut butter cup per day isn't enough for you — it's not for me — you can make your own from scratch. They're a great treat to share with friends around the holidays.

If you're more of a fan of classic chocolate than Reese's, you can get great Hershey flavor with the Kisses calendar—which is $5.99 at Target. Of course, there are plenty of Advent calendars out there that aren't candy-filled. But where's the fun in that?
